when writing a letter to a pen pal, what is the closing?

Please Write back?

That sentence is often used. <g>

But the closing should be:

Your friend, Celest

or

Sincerely, Celest

When writing a letter to a pen pal, the closing is the part where you end the letter and express your desire for a response. "Please write back" is a common closing phrase that politely asks your pen pal to reply to your letter. It indicates that you are interested in continuing the conversation and maintaining the correspondence.

However, it's important to note that there are various other closing options you can choose from depending on the tone and relationship you have with your pen pal. Some alternatives to "Please write back" include:

1. Sincerely,
2. Yours truly,
3. Best regards,
4. Warm wishes,
5. Take care,
6. Looking forward to hearing from you,

You can select a closing that matches the style and level of formality you wish to convey in your letter. Additionally, it's always thoughtful to include your name or a signature at the end of the letter before the closing.
